 When using the `<!--nextpage-->` tag one or multiple times in post,
 `wp_link_pages()` generates pagination links for the post. In the set of
 pagination links, `aria-current` would help assistive technologies users
 orientate themselves and understand which the current active "page" is.

 See also #40833 that introduced aria-current for in `paginate_links()`,
 typically used on archive pages for posts navigation.

 The actual links markup gets generated by `_wp_link_page()`. Worth noting
 this markup could be improved also for other things, for example there's
 no "current" CSS class used on the active paeg number.

 Themes usually add their own markup around the links to improve things a
 bit. For example, Twenty Seventeen uses this:

 {{{
 wp_link_pages( array(
         'before'      => '<div class="page-links">' . __( 'Pages:',
 'twentyseventeen' ),
         'after'       => '</div>',
         'link_before' => '<span class="page-number">',
         'link_after'  => '</span>',
 ) );
 }}}

 However, some improvements to the default output would be a nice
 improvement.
